Rectangular Coordinates in 3 D

How do 2-D properties relate in 3-D? Lead the class in a discussion on how to draw and see relationships of lines and planes in three dimensions. The ability to see these relationships is critical to the further study of volume and...

Go beyond the basic formulas and uncover the surface area and volume of 3-D shapes with this comprehensive and organized learning exercise packet. The problems include the basic formula computations while also challenging your learners...

How  does the shape of the surface of water in a container change as water leaks out? After tackling this question, learners take part in a similar activity with more complex figures.

Apply the Pythagorean Theorem in three-dimensional shapes. Young mathematicians watch a video that takes them through several examples of using the Pythagorean Theorem to solve problems involving lengths in three-dimensional figures. A...

It's about to get 3-D! The video shows your class how to expand the midpoint formula to find the midpoint of a three-dimensional segment. The example shown calculates the midpoint using the x-, y-, and z-coordinates.

Slice up solids. A portion of a geometry playlist introduces two conventional ways to visualize 3-D figures in 2-D. The resource defines cross-sections and nets and provides examples of both.

Let's move into the third dimension! Learners explore the vocabulary and notation related to three-dimensional figures. The video covers examples of pyramids, but the vocabulary is universal to all 3-D objects.

Math whizzes examine the relationship between area and volume and the relationship between a 3-D shape and its surface area. Following discussion and practice, pupils participate in a project in which they design packaging for a new...

The sky is the limit when printing custom 3-D shape templates from this site. Not only can you pick your shape and pattern, there is an option to upload an image for the different sides of the geometric shape. Let your learners have fun...

In this exercise, students practice using the Pythagorean Theorem to find the side lengths of triangles within a 3-D solid. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions...
